INV

Patented May 29, 1934 UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to Vises and more particularly to attachmentstherefor and has for the primary object the provision of a device of theabove stated character which may be easily and quickly applied to thejaws of a conventional type of vise for the purpose of gripping anobject or device upon four sides thereof.

Another object of the invention is the provision of means whereby adevice of irregular shape may be readily gripped. upon four sides orfaces thereof.

With these and other objects in view this invention consists in certainnovel features of construction, combination and arrangement of parts tobe hereinafter more fully described and claimed.

For a complete understanding of my inven-- tion, reference is to be hadto the following description and accompanying drawings in which Figure 1is a top plan view; illustrating a vise with an attachment appliedthereto and constructed in accordance with my invention.

Figure 2 is a side elevation illustrating the same,

Figure 3 is a sectional view taken on the line 33 of Figure 1.

Figure 4 is a perspective View illustrating one of the auxiliary jaws ofthe attachment.

Figure 5 is a similar view illustrating another auxiliary jaw of theattachment.

Figure 6 is a horizontal sectional view showing the pairs of auxiliaryjaws associated with each other and adjusted to grip a device ofirregular shape upon four sides thereof.

Figure 7 is an edge view illustrating one of the auxiliary jaws.

Figure 8 is a side view illustrating a dog for operation in conjunctionwith the jaw shown in Figure 7.

Figure 9 is a plan view illustrating an attachment for one of theauxiliary jaws.

Figure 10 is a perspective view illustrating the attachment.

Figure 11 is a detail sectional view illustrating :an attachment for oneof the auxiliary jaws.

Figure 12 is a perspective view illustrating the attachment for the jawshown in Figure 11.

Referring in detail to the drawings the numeral 1 indicates aconventional type of vise having the usual jaws 2 adjusted towards andfrom each other by the adjusting means 3. The jaws 2 upon their activefaces are provided with screw threaded sockets to receive stud bolts 4carried by pairs of auxiliary jaws 5 for the purpose of detachablyconnecting the latter to the jaws 2. The heads of the stud bolts arecountersunk in the auxiliary jaws 5 so as not to project beyond theiropposing or active faces. Each auxiliary jaw 5 is secured to therespective jaw 2 by a pair of stud bolts and are further provided withadditional openings and also the jaws 2 are provided with additionalsockets permitting an adjustment of the auxiliary jaws laterally withrespect to the vise. The auxiliary jaws are provided with slots 6 havingend converging walls 7. One wall of each slot 6 is offset, as shown at8, having the ends of the offset beveled, as shown at 9. The beveledends parallel the end converging walls 7 cooperating therewith informing converging channels or guides 10. The jaws 5 are of elongatedformation and have cooperating therewith pairs of auxiliary jaws 11 eachof substantially triangular shape, as shown in Figure 6. One face ofeach jaw 11 is provided with converging ribs 12 to be received in thegrooves 10 with the offset portion 8 operating between the grooves. Thejaws 5 move towards and from each other by the adjusting of the jaws 2of the vise towards and from each other and due to the slidableconnections between the jaws 5 and the jaws 11, the latter will movetowards and from each other during the adjustment of the jaws 5 towardsand from each other so that an object positioned between the pairs ofjaws 5 and 11 will be gripped upon four sides thereby efficientlyretaining the object against slipping.

The active face of one of the jaws 11 is recessed, as shown at 13, andpivotally mounted in said recess is an adjusting plate 14 provided witha slot 15 closed by a plate 16 having a keyhole slot 17. An adjustingrod 18 having feed threads meshes with feed threads of the last referredto jaw 11 and is provided with a ball or sphere 18' operating in thegroove 15 by the adjusting rod 18 extending through the keyhole slot 17.A finger piece 19 is carried by the adjusting rod 18 whereby the lattermay be rotated in either direction for moving the adjusting plate in andout of the recess 13. The adjusting plate 14 is employed for the purposeof gripping between the pairs of jaws 5 and 11 an object of irregularshape, as shown in Figure 6.

To facilitate the gripping of a round object by the auxiliary jaws 5 and11, removable blocks 20 are provided having pins 21 to fit in sockets 22formed in the jaws 11. The blocks have pointed ends 23 which projectslightly beyond the active faces of the jaws 11 to cooperate with thejaws 5 in gripping the round object.

To employ the attachment with only a pair of jaws, namely the jaws 5,the jaws 11 are removed from the jaws and facing blocks 24 are providedfor the purpose of closing the slots 6 in 5 the jaws 5. The ends of theblocks 24 are beveled to fit the converging walls '7 of the slots with aportion of said blocks projecting beyond the non-active faces of thejaws 5, as shown in Figure 11.

While I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in construction,combination and arrangement of parts may be made without departing fromthe spirit and scope of my invention, as claimed.

Having described the invention, I claim:

1. An attachment for a vise comprising pairs of jaws arranged to formtherebetween a space of rectangular shape to receive an object to begripped, means connecting one pair of jaws to the other pair of jaws forcausing said jaws to increase and decrease the size of the space betweensaid jaws by the adjustment of one pair of said jaws with respect toeach other, and means il-ii for securing the last-named pair of jaws tothe jaws of a vise.

2. An attachment for a vise comprising a pair of elongated jaws securedto the jaws of a vise and having slots provided with beveled end walls,

36 a pair of triangularly shaped jaws extending into the slots andengaging the beveled walls of said slots and cooperating with theelongated jaws in forming a space of rectangular shape to receive andgrip an object by the adjustment of the elon- 85 gated jaws with respectto one another through the adjustment of the vise.

3. An attachment for a vise comprising a pair of elongated auxiliaryjaws having slots, means H for adjustably and detachably connecting the40 f auxiliary jaws to jaws of a vise for movement verging end walls ofthe slots to form converging guideways, a pair of triangular shaped jawsreceived by the slots, and converging ribs formed on the triangularshaped jaws and fitting the guideways.

4. An attachment for a vise comprising a pair of elongated auxiliaryjaws having slots, means for adjustably and detachably connecting theauxiliary jaws to jaws of a vise for movement with the latter, saidslots having converging end walls and one wall of each slot offset toform a projection lying in the slot, said projections having beveledends cooperating with the converging end walls of the slots to formconverging guideways, a pair of triangular shaped jaws received by theslots, converging ribs formed on the triangular shaped jaws and fittingthe guideways, one of said triangular shaped jaws having a recess in itsactive gripping face, a plate pivoted to said last-named jaw and movableinto and out of the recess, and means for adjusting the plate towardsand from its respective jaw.

5. An attachment for a vise comprising pairs of elongated and triangularshaped auxiliary jaws, means for detachably and adjustably connectingthe elongated jaws to the jaws of a vise, said elongated jaws havingslots to receive the pair of triangular shaped jaws and the end walls ofsaid slots converging to engage converging faces of the triangularshaped jaws.

6. An attachment for a vise comprising pairs of elongated and triangularshaped auxiliary jaws, means for detachably and adjustably connectingthe elongated jaws to the jaws of a vise, said elongated jaws havingslots to receive the pair of triangular shaped jaws and the end walls ofsaid slots converging to engage converging faces of the triangularshaped jaws, and blocks removably secured to the triangular shaped jawsand having pointed ends projecting beyond the active gripping faces ofthe triangular shaped jaws.
